“…Incidentally Mumbai is the largest coastal city (also the financial capital) of India with several islands joined together by reclamation and having many heavy industries all around. In our earlier studies on heavy metal pollution status in major Indian cities, ambient air particulates and sewage sludge samples from Mumbai had shown higher pollutant contents compared to those from other metropolitan cities [35,36]. Arafa et al [11] have reported Br in the range 1.5-18.5 mg g À1 in Libyan fish.…”

Fish is the main food in coastal areas and its analysis for toxic metals has been used as an indicator of the pollution status of the aquatic environment. Several different fish species from the three Indian coasts, Visakhapatnam in the east, Mumbai in the west and Mangalore in the south west and also inland freshwater fish from Nagpur in the central region for comparison were analyzed for up to 20 elements (As, Au, Ba, Br, Cl, Co, Cr, Cu, Fe, Hg, K, Mn, Na, P, Rb, Sb, Sc, Se, Sr, Zn) by instrumental neutron activation analysis (INAA). Dried fish samples in powdered form were irradiated with thermal neutrons in a nuclear reactor followed by high resolution gamma ray spectrometry at different intervals. Several Reference Materials (RMs) of biological origin were analyzed for quality assurance and data validation. Elemental contents in different fish species vary in a wide range depending on the species, its size, location, and aquatic environment. Fish from Mangalore showed highest mean contents of Cr (14.8 AE 29.9 mg g À1 ), Cu (1005 AE 643 mg g À1 ) and Sb (849 AE 888 ng g À1 ) whereas those from Mumbai exhibited highest Hg (2066 AE 2146 ng g À1 ) and P (20.3 AE 4.63 mg g À1
